Abstract:

Invertebrates are a diverse group of animals that make up the majority of the animal kingdom and encompass a wide array of species with varying adaptations and characteristics. Invertebrates are found in nearly all of the world’s habitats, including aquatic, marine, and terrestrial environments. There are many misconceptions about invertebrate sentience, welfare requirements, the need for environmental enrichment, and overall care and husbandry for this amazing group of animals. This review addresses these topics and more for a select group of invertebrates with biomedical, economical, display, and human companionship importance.

Abstract:

We examined the influence of riparian vegetation patterns on coastal cutthroat trout Oncorhynchus clarki clarki diet and prey from the summer of 2001 through the spring of 2002. Benthic and drifting invertebrates, allochthonous prey, and fish diet were collected from deciduous, conifer, and mixed sections of three Oregon coastal watersheds. The nine sites were best characterized as a continuum of deciduous cover, and shrub cover and proportion of deciduous canopy were positively correlated (r = 0.74). Most sources of prey (benthic invertebrate biomass, allochthonous invertebrate inputs, aquatic and total invertebrate drift) and aquatic prey ingested by coastal cutthroat trout were greater where shrub cover was more abundant. Only aquatic drift, total invertebrate drift, and allochthonous invertebrates were positively correlated with deciduous vegetation. Compared with coniferous sites, allochthonous invertebrates under deciduous and mixed canopies were almost 30% more abundant. Stream discharge likely influenced seasonal fluxes of aquatic invertebrate biomass in the benthos and drift. Aquatic insects dominated gut contents during this study; however, terrestrial prey were most common in the diet during the summer and fall. In the Pacific northwest, systematic removal of deciduous riparian vegetation to promote conifers may have unintended consequences on food resources of coastal cutthroat trout and aquatic food web interactions.

Abstract:

This study aimed to determine the structure of invasive aquatic invertebrates through the approach, diversity, similarity, dominance, distribution, and comparison of invasive aquatic invertebrates with coral cover in coral reef ecosystems in PISISI KKPD. This research was conducted in September 2019 using the purposive sampling method to research points, collecting invasive aquatic data used the belt transect method and collecting coral reef data used the Point Intercept Transect (PIT) method. The results of the study found that the structure of invasive aquatic invertebrates in KKPD PISISI was in the good category indicated by the density invasive aquatic invertebrates of 39.67 individuals/m2, the biodiversity index was 1.50 with the medium category, the similarity index is 1.06 in the high category and the dominance index is 0.44 in the low category. The distribution of invasive aquatic invertebrates in the PISISI KKPD includes a cluster distribution. The highest value of invasive invertebrate water was 12.83 ind/m2 and the proportion of coral cover was 29.83% and the lowest was 3.67 ind/m2 and the proportion of coral cover was 54.67% showing the effect of invasive aquatic invertebrates on the proportion of coral cover.

Abstract:

Abstract Aquatic invertebrate data are useful for assessing wetland community structure, function, and water quality. Although collecting samples of aquatic invertebrates is relatively efficient and economical, processing these samples can be time consumptive and costly. Accordingly, researchers have devised methods to increase processing efficiency and effectiveness. For example, supersaturated solutions of solutes in various aqueous media have been used to separate invertebrates from aquatic media and organic matter. However, no study has evaluated this method for extracting invertebrates from sweep-net samples from flooded bottomland hardwood forests. We compared invertebrate recovery rates from samples processed using 1) tap water (control), 2) a supersaturated solution of sugar and water, and 3) a supersaturated solution of salt and water. We also evaluated a subsampling procedure by comparing taxonomic Order-level richness and Shannon diversity between sub- and whole samples. Numbers and dry biomass of invertebrates recovered were similar among the three aforementioned treatments. Use of supersaturated solutions did not reduce processing time, because invertebrates and leaf litter both floated instead of separating. Thus, we recommend using only tap water in processing sweep-net samples of invertebrates from forested wetlands that contain abundant leaf litter. Overall, we recovered 72.2% (95% CI = 3.0%) of all detected invertebrates and 48.0% (95% CI = 7.5%) of invertebrate biomass. Invertebrates that weighed less than others (e.g., mosquito larvae; Diptera) were more efficiently recovered than were heavier taxa (e.g., snails; Pulmonata). Our subsampling method underestimated Order-level richness and diversity indexes by 12% and 19%, respectively. However, processing subsamples was nearly two times faster than processing whole samples. Our method of using a sieve to subsample invertebrates is appropriate when numerical abundances are desired, because most (70%) invertebrates were detected and recovered.

Abstract:

The main aim of this study was to investigate the abundance of invertebrates in groundwater in relation to groundwater conditions (groundwater table, discharge, rainfall, and physio-chemical parameters), and to examine the suitable time for invertebrate sampling in springs. Thus, eight springs in two separate study areas, “Baumberge” and “Schöppinger Berg” (Münsterland area, North-Rhine Westphalia in Germany), were sampled five times (24 h for 2–5 consecutive sampling days) between November 2018 and October 2019. The results showed high spatial and temporal variance. In general, the existence of invertebrates and stygobites increased, whereas invertebrate types decreased with increasing hydraulic head and spring discharge. Therefore, investigating the abundance of invertebrates and invertebrate species is recommended to be done separately. Abundance of invertebrates was affected by different factors in both areas. Spearman correlation test (two-tailed) and factor analyses (n = 80, p ≤ 0.01) highlighted the importance of detritus as the main controlling factor for invertebrate existence and stygobite individuals in Baumberge, whereas dissolved oxygen is essential for their existence in Schöppinger Berg.

Abstract:

Exotic pine invasion affects native wetland communities in the Southern Hemisphere by changing the hydrological regimen and physicochemical characteristics. Studies evaluating the emergence of aquatic invertebrates from dormant stages are vital to identify the resilience of aquatic communities in ponds invaded by exotic pine species. In the present study, we tested the hypotheses that: (1) pine invasion decreases the richness of drought-resistant aquatic invertebrates in ponds; (2) pine invasion modifies the invertebrate composition in ponds; and (3) these differences in species composition (β diversity) are associated primarily with species turnover. Dry sediment samples were collected from three natural ponds in native grassland and three ponds in a pine invasion matrix in southern Brazil. In all, 7205 invertebrates, primarily represented by cladocerans (18 species), were sampled after rewetting dry sediments. Pine invasion decreased the richness of aquatic invertebrates because the natural ponds had almost 60% more species and a higher number of estimated species than the pine ponds. The composition differed between natural and pine ponds, and this difference in species composition (β diversity) was associated primarily with the replacement of some species by others. The presence of pine appears to alter colonisation and survival rates of aquatic invertebrates that aestivate in dry sediments in southern Brazil wetlands.

Abstract:

AbstractMany nearshore ecosystems are modified by aquaculture, including bivalve culture to produce food and restore extirpated populations. Small invertebrates in nearshore ecosystems support fundamental ecological processes, but the effects of bivalve culture on invertebrates are incompletely understood. Here, we compared invertebrate assemblages from multiple studies of bivalve-cultivated and unmodified nearshore habitats along the US west coast. In general, unmodified eelgrass and nearby off-bottom culture habitats with eelgrass present were inhabited by a greater abundance, richness, and diversity of epibenthic invertebrates than bottom culture and bare (mud, sand) habitats that both lacked eelgrass. Findings of individual studies suggested: minor differences in epibenthic invertebrate assemblages associated with various aquaculture practices; restoring native oysters to mudflats did not detectably alter epibenthic invertebrate abundances; epibenthic invertebrates were more abundant on shell hash introduced to mudflats than unmodified mudflats; and benthic invertebrates were less abundant, rich, and diverse in habitats cultured on bottom by Manila clams. Considering the range of these patterns, there appears to be potential for coastal communities to restore extirpated bivalve populations or develop bivalve culture practices that meet objectives to grow food while maintaining nearshore ecosystems’ fundamental processes supported by robust invertebrate assemblages.

Abstract:

Aquatic macrophytes are the main producers of organic matter in shallow aquatic ecosystems. They are also food sources for many herbivores. When macrophytes die, they enter the debris chain, are conditioned by microbial action and colonized by benthic invertebrates which remobilize nutrients from their biomass. In subtropical aquatic systems, the participation of shredder invertebrates has been questioned, highlighting the participation of fungi and bacteria in the degradation of organic matter. This study evaluated the degradation of two submerged aquatic macrophytes, Mayaca fluviatilis and Stuckenia pectinata, determining the quality of debris and microbiota and invertebrate trophic group density throughout the degradation process. Our results indicated that plants with lower polyphenol concentrations had higher degradation speeds. The shredders invertebrates had reduced abundance in both macrophytes, emphasizing the importance of bacteria and fungi in the nutrient cycling process in subtropical shallow lakes.

Abstract:

New data on aquatic invertebrates of the spring ecosystems of the Minsk region are presented. 104 lowest defined taxa (LDT) species and forms of representatives of macrozoobenthos and pleistone complexes belonging to 4 phyla of aquatic invertebrates were found: Platyhelminthes – 2, Mollusca – 20, Annelida – 7, Arthropoda – 75 species and forms. 75 taxonomic elements have been identified before the species. The average number of identified aquatic invertebrate species in the studied springs of the Minsk region was 12‒13 species, and the number of 205 specimens. The sources are inhabited by protected species of animals listed in the Red Book of Belarus and the Red Lists of a number of Western European countries. It was concluded that the fauna of aquatic invertebrate animals is rich and represented by a number of species rare in Belarus and Europe.

Abstract:

World-wide, invertebrates are found in most drinking water networks; however, limited data and information are available on the occurrence of invertebrates throughout the purification process. During this investigation, temporal and spatial variations in the invertebrate composition occurring throughout a conventional Drinking Water Purification Plant (DWPP) and the abiotic drivers responsible for their occurrence were investigated. Samples destined for invertebrate and water quality analyses were collected and multivariate statistical analysis was performed on the data obtained. Copepoda, Rotatoria, Cladocera, Ostracoda and Diptera were the dominant groups found in the source water and occurred throughout the purification process. A higher total biomass occurred throughout the purification process, in particular after sedimentation and filtration, compared with the total biomass entering the DWPP. The water quality variables measured were within the optimum ranges of invertebrates. The present study proved the theory that purification plants are an important source of invertebrates occurring in the drinking water distribution network. Strategies should be implemented to improve coagulation (by using coagulants/flocculants to increase the pH above 10.5), flocculation, sedimentation (by removing sludge and algae) and filtration (by optimizing filter bed maintenance) and general filter house ‘housekeeping’.

Abstract:

This thesis explored the uptake into the freshwater shrimp (Gammarus pulex) and the water boatman (Notonecta glauca) of key pharmaceuticals drawn from different therapeutic classes and covering a range of physico-chemical properties. For one compound, uptake was also assessed using the freshwater snail Planobarius corneus. In G. pulex, bioconcentration factors (BCFs) ranged from 4.6 – 185900 and increased in the order moclobemide < 5-fluoruracil < carbamazepine < diazepam < carvedilol < fluoxetine. In N. glauca BCFs ranged from 0.1 – 1.6 and increased in the order 5-fluorouracil < carbamazepine < moclobemide < diazepam < fluoxetine < carvedilol. For P. corneus, the BCF for carvedilol was 57.3. The metabolism of the study pharmaceuticals in the shrimp was investigated. Diazepam was found to be metabolized by G. pulex and a metabolite was detected and tentatively identified as nordiazepam. For the other five study compounds no metabolites were observed and it was inferred that metabolism in G. pulex may not influence the BCF. The influence of dietary uptake was explored in the test organisms with carvedilol and fluoxetine. It was found that uptake from water was the predominant route of exposure for G. pulex but the data for N. glauca was contrasting and the exposure from the food was predominant. In both organisms a combination of food and water exposure resulted in a higher uptake of the compounds. The differences in degree of uptake from water across the organisms may be due to differences in mode of respiration, behaviour and the pH of the test system. The differences in degree of uptake from food across the organisms may be due to differences in feeding strategies. The degree of uptake of pharmaceuticals within an organism was related to the hydrophobicity of the pharmaceuticals.

Abstract:

Freshwater environments are threatened worldwide by external stressors and biodiversity decline, with major implications for ecosystem resilience. The genetic consequences so far have been neglected, especially for freshwater invertebrates, though their abundance, diversity, ease of sampling and functional importance renders them ideal candidates for genetic appraisal. For three freshwater invertebrates (Amphinemura sulcicollis, Isoperla grammatica and Baetis rhodani) novel microsatellite markers were developed so that genetic structure, and genetic diversity could be assessed throughout upland Wales. The aim was to investigate dispersal and the genetic response to environmental stressors. Genetic diversity in these species was compared to species diversity across whole macroinvertebrate assemblages to investigate what factors might cause a correlation between these fundamental levels of biodiversity. The demographic history of each species was also investigated with the aim of assessing whether reduced genetic diversity was due to bottlenecks and more broadly, what this indicates in terms of the populations’ resilience. Species differed in their genetic structure and genetic diversity. All three species showed effective dispersal and geneflow, with each species displaying panmixa across catchments in southern and mid-Wales. However, A. sulcicollis and I. grammatica revealed genetic isolation and reduced genetic diversity at specific northern sites. Genetic and species diversity were correlated positively only in A. sulcicollis, where isolation combined with a common driver were the likely cause. There was evidence of recent bottlenecks in all three species. All these results could be explained by an underlying genetic response to post-industrial acidification: reduced genetic diversity correlated significantly with acidity for A. sulcicollis, while reduced species diversity and genetic bottleneck signatures was consistent with chronic and episodic acidification across the Welsh region. Overall, these results show how a positive correlation between species and genetic diversity can never be assumed, and illustrate how assessments of genetic health expand insights available from traditional biodiversity assessment.

Abstract:

The aim of the study is to assess the effects of six weirs towards the macroinvertebrates and to establish methodology for selection of priority weirs for removal. Macroinvertebrates were collected from 12 sampling sites on the rivers Kriva Reka (2), Pcinja (8) and Kumanovska Reka (2) upstream and downstream of selected weirs. The degree of similarity of the macroinvertebrates above and below the weirs was used as ecological criteria to participate in determining which weirs could be subject to removal or could remain unchanged. Results showed that only weir below the city of Kriva Palanka could be subject to removal.

Abstract:

Squid are the fastest aquatic invertebrates through jetting locomotion. This done through a mantle that quickly compresses an internal fluid, forcing fluid out through a funnel. The squid mantle has a complex collagen fiber and muscular system and squid propulsion is primarily done through circumferential muscles (90°) contracting around the mantel, forcing fluid out of the mantel. However, jetting is also increased through elastic energy stored in the helically-wound IM-1 collagen fibers, which have been measured between 28° to 32° in different species of squid. Inspired by the muscular and collagen fiber configuration found in the squid mantel, new composite pumps with active fibers oriented at precise angles around a cylindrical tube are proposed. An analytical model of the active fiber composite pump is developed. Results show that maximum pumping power and efficiency is achieved with a wind angle of 90° and a matrix modulus that is equal to the fiber modulus.

Abstract:

Dorsoventral undulation is adopted by aquatic mammals for propulsion. However, it is not too common to find invertebrate aquatic animals that undulate their bodies in the vertical plane, which results from antiphasic contractions of dorsal and ventral muscles. To explore the mechanisms of the soft-bodied propulsion, in this work, an annelid swimmer employing up and down undulatory swimming mode is chosen, and the related kinematics and hydrodynamics are studied using a combined experimental and computational approach. A fully calibrated photogrammetry system with three highspeed cameras from different views is used to record the forward swimming motion of this invertebrate swimmer, namely leech. The vertically undulating kinematics are then reconstructed from those videos. With the detailed reconstruction, the undulating wavelength and amplitude distribution the swimmer exhibits during propulsion are quantified. Kinematics analysis results show that the invertebrate swimmer swims in a vertical anguilliform mode and the wavelength is about 0.7BL (body length) when it swims at a velocity of 1.5BL/s. An in-house immersed-boundary-method based flow solver is used to conduct the numerical simulations, with which the hydrodynamic performance and wake structures are investigated. The thrust generation and power consumption of the undulating body are described quantitatively. Furthermore, along the undulating body, the pressure distributions are studied.

Abstract:

In Romania, near the Black Sea are two Natural Reservations lakes with salt water, Techirghiol, and Mangalia nowadays confronted with new environmental issues. Lake never freezes. Under these conditions, there are always birds in transit or in wintering; some of them protected species as endangered. There are no known or available solutions at present that can be used here, without disturbing the biological balance. This paper presents a prototype, patent pending in Romania, which has achieved significant results in protection of the natural environment. The prototype is an autonomous pilot station, placed on a mobile pontoon, powered by photovoltaic panels. It can collect and partially dry the aquatic vegetation developed in excess due to eutrophication. The harvested vegetation is used as the biomass resource to warm the Research Centre on shore, the greenhouse for the protected plant species and the poultry incubator. The prototype now is implemented in Techirghiol Lake as to diminish the local environmental problems: the massive mass of vegetation, the invasive species that appeared, as the invertebrates, the interference scallops, and the predator fish. Due to the permanent decreasing the number of the specific fish, all bird colonies are affected. The proposed solution is innovative, perfect ecological and energetic independent. The mobile pontoon is commanded from distance. The solar panels ensure the pontoon movement and the supply of the collecting, compacting, and partially drying the vegetation. The detailed functioning of the prototype is further detailed presented. The main advantage of this solution is that the vegetation can be collected during the entire period of vegetation without disturbing the biologic environmental, nests period of construction, laying eggs, rearing birds, etc. A second major advantage is that the extracted vegetation can be consumed immediately and integrally into a biomass power plant. The third advantage of this technology is that the platform is placed on a mobile pontoon energetically independent, entirely automated and with a constant adaptation of the operating parameters in accordance with climatic conditions. This innovative solution is accordance to the Romanian reply for EU Council Directives, UE EUCO 75/13 CO EUR 7 signed in Brussels at 22/05/2013, referring to the promotion of the new solutions based on utilization of renewable technology with environmental effects. The prototype has a multi- and a cross-disciplinary character due to the main components. It represents a powerful applicative research requested and co-financed by the National Authorities and the private sector, as to solve this problem appeared into these Natural Reservations.

Abstract:

Findlay Creek is a small, coldwater stream which was crossed by a natural gas pipeline using conventional open-cut techniques in late August 1992. Pipeline crossing activities included the removal of a beaver dam which was located along the proposed alignment, the installation of a temporary road crossing, and the actual pipeline installation. A monitoring study was initiated to examine the impacts of pipeline construction on this stream including changes in the physical and biological regimes of the aquatic ecosystem. Results of this study indicate that the dramatic sediment loads (suspended sediment levels of up to 3000 mg/L) caused by pipeline construction were sufficient to cause changes to the channel morphology as well as the fish and invertebrate communities. By twelve weeks post-construction, partial recovery of habitats and aquatic communities was apparent. Changes to the physical channel parameters and the stream population structure documented in this study suggest that impacts to Findlay Creek were localized, and full recovery was documented in affected areas by the one year post construction sampling period. This study concurs with other research investigating the impacts of pipeline construction, in that impacts on the aquatic fauna appear to be localized in extent and short term in duration.

Abstract:

With the ongoing anthropogenic eutrophication of the Lake Baikal there is an increase in the abundance not only of aquatic vegetation, but also organismsconsumers. As consumers of vegetable detritus are crustaceans – amphipods, which, by eating detritus, partially reduce the pollution of the lake with rotting organic matter. A significant increase in their number is evidenced by the increase in the abundance of amphipods in the nocturnal migratory complex in the coastal pelagic zone.

Abstract:

Monitoring ecosystems is vital to understanding trends over time and key to detecting change so that managers can address perturbations. Freshwater streams are the lifeblood of the surrounding landscape, and their health is a measure of the overall watershed integrity. Streams are the culmination of upland processes and inputs. Degradation on the landscape as well as changes to the stream itself can be detected using biota living in these ecosystems. Aquatic invertebrates are excellent indicators of ecosystem quality because they are relatively long-lived, sessile, diverse, abundant and their tolerance to perturbation differs. Aquatic invertebrates were monitored at three sites along the Niobrara River at Agate Fossil Beds National Monument in 2019 completing 23 years of data using Hester-Dendy and Hess samplers. Hess samplers are artificial multi-plate samplers suspended in the water column to allow invertebrates to colonize and Hess samples collect invertebrates in a known area on natural substrate and vegetation. We identified 45 invertebrate taxa from four phyla (Annelida, Arthropoda, Mollusca, Nematoda) using both samplers in the Niobrara River (Appendix A and B). Hester-Dendy samplers collected 4 taxa not found in Hess samples and Hess samples collected 17 taxa not collected with Hester-Dendy samplers. Hess samples captured more (91%) than Hester-Dendy samples (62%). Crustacea, Diptera and Ephemeroptera were the most abundant groups of invertebrates collected in the Niobrara River. The proportion of Insecta, Annelida, Trichoptera and Diptera differed between Hester-Dendy and Hess samples (p < 0.05). EPT richness, proportion EPT taxa and Hilsenhoff’s Biotic Index (HBI) (p < 0.0001) differed between sampler types, but taxa richness, taxa diversity and evenness (p > 0.29) did not. We collected the highest density of invertebrates at the Agate Middle site. Agate Spring Ranch had the lowest taxa richness and HBI, and the highest proportion of EPT taxa. HBI at the sites ranged from 4.0 to 6.3 (very good to fair from Hilsenhoff 1987) using the Hester-Dendy and 5.2 to 6.9 (good to fairly poor from Hilsenhoff 1987) using the Hess sampler.

Abstract:

Dousman Creek, located in northeastern Iowa, is a Class ?B? coldwater stream that supports a trout population and is listed among the Outstanding Iowa Waters (Iowa Department of Natural Resources 2010, 2016). The Heartland Inventory and Monitoring Network (Heartland Network) of the National Park Service (NPS) has been monitoring aquatic communities (fish and invertebrates) in Dousman Creek within Effigy Mounds National Monument (NM) since 2008. Corresponding physical habitat and water quality were also collected during biotic sampling. The objectives of this long-term monitoring program are to assess the status and trends in the biotic stream community and relate these trends to environmental variables. The purpose of this report is to summarize the baseline aquatic community data collected during three sampling events conducted from 2008 to 2017. The fish community was dominated by the intolerant cool/cold-water species Brown trout (Salmo trutta) and Mottled sculpin (Cottus bairdii) in 2008, while more tolerant white sucker (Catostomus comersonii) and Johnny darter (Etheostoma nigrum) were most abundant in 2014. During 2017, fish community composition was more evenly distributed among species present. Benthic invertebrate samples were dominated by the moderately intolerant mayfly genus Pseudocloeon and blackfly genus Simulium in 2008 and 2014, while the invertebrate samples in 2017 were dominated primarily by a tolerant, mayfly taxa (Baetis) and Oligochaetes. The abundance of aquatic invertebrates in 2017 was more than ten times lower than invertebrate abundance in 2008 and 2014. Water quality data collected by the Heartland Network did not indicate any of the five parameters (temperature, dissolved oxygen, pH, specific conductance, or turbidity) exceeded the Iowa Department of Natural Resources water quality standards, however the number of hourly measurements were low (4?20 measurements) depending on year sampled. Three years of data are currently insufficient to fully characterize the stream integrity of Dousman Creek based on fish and invertebrate communities. Continued long-term monitoring of Dousman Creek will allow for better assessment of the biotic integrity and overall quality of the stream.

Abstract:

The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and ecosystem health are dependent on processes occurring in the entire watershed as well as riparian and floodplain areas; therefore, they cannot be manipulated independently of this interrelationship. Land use activities—such as timber management, landfills, grazing, confined animal feeding operations, urbanization, stream channelization, removal of riparian vegetation and gravel, and mineral and metals mining—threaten stream quality. Accordingly, the framework for this aquatic monitoring is directed towards maintaining the ecological integrity of the streams in those parks. Invertebrates are an important tool for understanding and detecting changes in ecosystem integrity, and they can be used to reflect cumulative impacts that cannot otherwise be detected through traditional water quality monitoring. The broad diversity of invertebrate species occurring in aquatic systems similarly demonstrates a broad range of responses to different environmental stressors. Benthic invertebrates are sensitive to the wide variety of impacts that influence Ozark streams. Benthic invertebrate community structure can be quantified to reflect stream integrity in several ways, including the absence of pollution sensitive taxa, dominance by a particular taxon combined with low overall taxa richness, or appreciable shifts in community composition relative to reference condition. Furthermore, changes in the diversity and community structure of benthic invertebrates are relatively simple to communicate to resource managers and the public. To assess the natural and anthropo-genic processes influencing invertebrate communities, this protocol has been designed to incorporate the spatial relationship of benthic invertebrates with their local habitat including substrate size and embeddedness, and water quality parameters (temperature, dissolved oxygen, pH, specific conductance, and turbidity). Rigid quality control and quality assurance are used to ensure maximum data integrity. Detailed standard operating procedures (SOPs) and supporting information are associated with this protocol.

Abstract:

Land use changes that degrade water quality and stream habitat can negatively impact aquatic communities. Monitoring trends in aquatic community composition and habitat conditions is a robust way to assess stream integrity and health. Herbert Hoover National Historic Site (NHS) is in eastern Iowa where dominant land use consists of row-crop and grassland agriculture. A portion of an unnamed tributary of the West Branch of Wapsinonoc Creek, known as Hoover Creek, flows through the park. In 2008, the Heartland Inventory and Monitoring Network (Heartland Network) of the National Park Service (NPS) began monitoring aquatic communities (fish and invertebrates), physical habitat, and water quality at Hoover Creek within the park. This report summarizes four years of data to assess the baseline conditions of Hoover Creek within Herbert Hoover NHS. Aquatic invertebrate taxa richness ranged from 21 to 32 among all years monitored. Three of these taxa are sensitive to poor water quality and habitat conditions. The invertebrate community was dominated by true flies in the Chironomidae family, Oligochaete worms, and mayflies in the Baetidae family. These taxa are all tolerant of poor water quality and habitat conditions. However, in 2011, the sensitive caddisfly Ceratopsyche was also abundant. Mean Hilsenhoff Biotic Index values indicated the invertebrate community fluctuated over time, ranging from fairly poor in 2017 to good condition in 2011. Ten fish species were collected at Hoover Creek across the four years sampled with seven of those species found in all years. All fish species collected were either moderately tolerant or tolerant to poor habitat and water quality conditions; the community was dominated by johnny darter (Etheostoma nigrum), creek chub (Semotilus atromaculatus), and blacknose dace (Rhinichthys atratulus). Based on the Index of Biotic Integrity developed for Iowa streams, the fish community ranged from fair condition in 2008, 2014, and 2017 to good condition in 2011. Hoover Creek was found to have predominately fine to medium gravel substrate with high embeddedness, and banks were steep and tall and consisted of fine silt substrate. With the exception of turbidity after a rain event in 2008, water quality parameters were within state standards. The four years of stream biota data coupled with habitat data should form a good baseline for assessing changes or trends in the aquatic community and overall stream health of Hoover Creek.

Full text

Abstract:

Stands of emergent vegetation such as the common reed (Phragmites australis) and members of the genus Typha are a key part of many freshwater and brackish shoreline ecosystems. Similar to trees in a forest, these macrophytes provide structural complexity, a source of food, and shelter from harsher abiotic conditions supporting a broad range of flora and fauna. However, in recent years, anthropogenic activities have facilitated these species to dominate their native ecosystems, forming increasingly homogenous reed beds, and furthermore to invade many non native habitats. In this text, I review the ecological interactions of habitat forming emergent vegetation with an emphasis on other macrophytes, fish, birds and invertebrates. Trends in literature highlight both the importance of emergent vegetation to aquatic ecosystems, but also the negative impact they can have when invading, or forming dense homogenous stands. The competitive exclusion of other macrophytes and physical reduction of space within stands of emergent vegetation are the main drivers that negate or reverse most of the beneficial ecological interactions of reed or Typha with other organisms. I also detail how various management practices have attempted to address the presented issues, with the most successful methods being those that aim to promote heterogeneity. While progress has been made, future studies should focus on the identification of optimal management practices, to pave the way for more effective conservation applications.
